I do NOT own Avatar, or Golden Sun.

Dreams of The Overworld

-Are you sure he's the right one?

-If he's not, we're both doomed…

-You must go to him. He must help-

-Yah, I know, ok? But I need time… It will be hard enough just getting ot his world, I may not have enough power… I may even die.

-Why are you always so calm?

-Being otherwise would only get in the way…

-But you're never not calm. Doesn't it get boring?

-Boring? I've been stuck underground for two thousand years, I've grown immune to boredom.

-Well, get to sleep, you need to rest, and I need to show you something. The Avatar is very, uh, dark nowadays. You should see why.

-What exactly does that have to do with me sleeping?

-You'll see…

-Well, all I'm saying is you better be right. For my sake, and yours. And soon, I'll have my revenge…

Under The Earth Kingdom

One week after the fall of the Earth Kingdom…..

"Are you sure about this Aang?" Katara asked, turning one last time to him.

"Would you leave him alone, sis? He's as worried as the rest of us, ok?" Sokka said, also turning around.

"Yah, there's no turning back now, Katara, so please, let's do this…" Aang said, continuing on past her. They were underground, and Toph and Aang were tunneling through the rock. They had made a plan as soon as Aang was better. It was simple, yet effective, as Sokka put it. They would tunnel directly under the throne room, and attack Azula. They had been slowed by Katara's constant worrying. Suddenly, Toph stopped.

"We're here. Now, we go up," she said. Aang nodded, and they thrust their hands upwards. The four of them rose steadily, moving through the solid rock.

"Now, when we get up there, you three go directly for Azula's guards, Toph, take out any Di-li in the immediate are, and I'll go into the Avatar state. Remember, leave her to me. I'm not risking one of you getting- "

He cut off as suddenly the rock above him was un-bendable. Toph stopped, too.

"What is this?" Aang asked.

"Metal," Toph said. "But what is it doing here? We're directly under the city?"

"I don't know, but let's go around it, and keep moving," Sokka said. "I don't like this."

"I have a better idea," Toph said. She reached up, and crunched her hands into the metal, and ripped it open. They all climbed through the hole in the metal, Sokka going reluctantly.

What they saw was shocking…

It was a large room that looked like some sort of lab. It had a table in the center with chains hanging from it. The walls were covered in pure, shiny metal, and from the ceiling hung a huge structure. It was a frame of some kind, shaped like an upside-down cone, pointed at the center at the table.

But parts of the lab were missing, and the huge cone-structure looked like it was unfinished.

"What is it?" Katara asked.

"It must be some sort of torture chamber, look at that table," Sokka said. "It looks like somebody could be chained to it." They all looked at the room in awe, subconsciously getting closer to each other. Suddenly, Toph said, "Somebody's coming, quick!"

She pushed them towards the hole, and they all jumped in. Toph turned and smoothed the metal out where the hole had been. They listened as best they could through the metal.

"How much longer until it's ready?" asked a female voice.

"It won't take much more than a day now, it's nearly ready," answered a deep, male voice.

"That soon? Excellent." The voice faded away, and the four of them heard a door slam.

"Well, whatever that was, let's get out of here." Aang said. Toph nodded, and they bent around the metal room. They found out that there was also a tunnel leading down to the lab, which was also made of metal. They followed this up almost all the way to the throne room. Just below it, Toph stopped.

"Ok, we're only a few feet below the room…" She whispered.

"Then let's do this," Aang said. He closed his eyes, and concentrated. They watched as his tattoos started to glow, and when he opened his eyes, they were glowing, too.

"Let's do this," he repeated, this time in that mix of his voice, and the avatars'. And with that, Toph launched them up into the room.
